Climate change causing oceanic boundary currents to intensify and shift poleward

 ZA,
Weather along the eastern coasts of South Africa, Asia, Australasia and South America will get significantly warmer and stormier on average over the next 100 years, a new study finds. The culprit? Climate changes that are causing ocean currents next to these coastal regions, called western boundary currents, to become stronger and extend further toward the poles, according to the new

Wind-Blown Antarctic Sea Ice Helps Drive Ocean Circulation

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone

Saturn moon Enceladus’ ice shell likely thinner than expected

A vast ocean of water beneath the icy crust of Saturn’s moon Enceladus may be more accessible than previously thought, according to new research. A new study has revealed that near the moon’s poles, the ice covering Enceladus could be just two kilometers (one mile) thick—the thinnest known ice shell of any ocean-covered moon. The discovery not only changes scientists’ understanding of Enceladus’ structure, but also makes the moon a more appealing target for future exploration, [...]

A new study finds that in a Phoenix suburb, homeowners’ associations are good for water conservation. According to the study, homes in HOAs in Goodyear, Arizona use up to 17,000 fewer liters of water (4490 gallons) in the peak month of July compared to their non-HOA counterparts, roughly the amount needed to fill eleven hot

Classification of earthquake-induced landslide event sizes

  Some weeks ago we published a new study on the classification of earthquake-induced landslide event sizes based on seismotectonic, topographic, climatic and geologic factors. Our idea was that this classification could be used to help improve seismic hazard assessment by contributing to a better prediction of landslide hazards induced by an earthquake when the geologic, topographic and climatic context is well defined. Possible applications could be the short-term prediction right after [...]

  NASA has a press release out about a new study published  in the AGU’s Journal of Geophysical Research: Solid Earth. From the press release: New Orleans and surrounding areas continue to sink at highly variable rates due to a combination of natural geologic and human-induced processes, finds a new NASA/university study using NASA airborne radar. The observed rates of sinking, otherwise known as subsidence, were generally consistent with, but

Iron Fertilization Won’t Work in Equatorial Pacific, Study Suggests

Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of carbon-capturing algae, but a new study shows that the excess iron had little to no

Some research suggests that, along with melting ice sheets and glaciers, the water pumped from underground for irrigation and other uses, on the rise worldwide, could contribute substantially to rising sea levels over the next 50 years. A new study published in Nature Climate Change says the magnitude is substantially

The southeastern United States should has seen some notable seismic events – most recently, the 2011 magnitude-5.8 earthquake near Mineral, Virginia that shook the nation’s capital.

After 50 years, scientists think they may have cracked one of atmospheric science’s most persistent mysteries. Every day at dawn, an unknown phenomenon appears. Radar waves bounce off of it and return to radar receivers like an echo. Now, a pair of researchers at Boston University hypothesize that the sun could be causing the inexplicable
